TESLA Electric Truck?

[Big Barn]

Soon one will read about bad manners and leaving your already charged EV in place at the charging station. I mean, you could unplug it (could you?) but the vehicle would still be in the way.

That’s a common occurrence around here as I am certain it is everywhere. Bad behaviour is pretty universal....

 

[Gale Hawkins]

Bad behavior is universal. The local Ford dealership has offered free use of their J1772 240 volt charging connection for years that is between their showroom and shop doors. Now there is a No Tesla charging except on weekends sign up. From time to time a Telsa would be left plugged in overnight and still be there unattended during business hours the morning. The nice thing about a Tesla charging on a J1772 charge station is they can not lock the charging cord to their car but just their Tesla provided J1772 adapter.

I only use the free ones in the area to insure I can get home with a margin of safety range so adding 10-20 miles does not take long when the level of charge is very low. I was given permission to use these free chargers before I used them and most often I just sit in the car and I never lock the charging cable to be on the safe side should they have a business need for the chargers. One can reach the spot in front of the charging station and the parking spot on either side. The utility company's charger is in the front parking lot and they do have some F-150 hybrids and one manager had a Leaf at one time I was told. The cord on that charger will reach 5 parking spots. When I use that charger I put a $2 charge on my meter base when I get the car to my home charger.

The EA charges at Walmart with the 50 amp CHAdeMO is $0.21 per minute of use with 10 minutes of grace after you get the text the charging is complete. After 10 minutes of grace your card starts being charged at the rate of $0.40 until you physically remove the charging cable from your EV.

If I had to use my Telsa Tap with an Tesla Destination charger I would lock it if I had to leave the car due to its cost but would want to go down and move away after getting the charge that I needed for the next day in case someone checked in late that was low on charge. Some could still unplug the Tesla Destination charger from my Tesla Tap and start using it.

Again for about 99% of the time I do not have a need for charging stations because it is such a no brainer to charge while I sleep at home. I think a lot of people was like me a few months ago and think public charging stations are needed for daily commutes. That seldom is the case I now understand.

There was no way I was going to learn the ropes of EV ownership and usage without putting money on the line to get an EV.

Now I never plan to be without an EV going forward. By the time there are $30K EV's with 300 miles of range charging stations will not be of much concern to most which is not the case with a range of 75 miles today.

You don't have the vid memorized by now?

Not with you right in front all the time.

 

[Grumpycat]

Are there any situations where a HV extension cord with Supercharger ends would be useful?

Not really. The plug and socket are unique. Plus it would have to carry 400VDC @ 350A, not just be "rated for".

 

[Gale Hawkins]

Still dreaming about her college vid?

You guys have too much free time. She does have some bounce in her step. She seems like the EV type but I have heard otherwise. Maybe she will go for a Tesla electric truck someday.

But it was true that AOC thought an EV could plug into itself and keep driving. There were internet pictures proving it. :laughing:

That's not hard to believe. I'm running into people that believe all electric cars use gas to charge the battery.

I'm going to start telling them EV's are powered like their cell phone. If you don't want to walk then you have to plug them in to an outlet from time to time like they do their cell phone from time to time if they want to talk on it.

 

[Industrial Toys]

Surely you won't have 400 volt at 350 amps at home. There must be avenue for charging with a generator. If it takes 30 minutes and gets you 20 miles farther down the road, that may be enough to save the day. If I couldn't do something like that, I probably wouldn't be interested.

in a few years I really think there will be a shift to wireless vehicle charging

The MG Electric Marvel X is supposed to have wireless charging ability.

They are working on level 3-4 autonomy and with some programming should be able to be parked at the charging parking space and using the mobility services apps.

Charge the vehicle as the driver does other things then be summoned to pick up the driver leaving the wireless station ready immediately after the desired level of charge has been reached.
Ready for the next drivers car or maybe even fully autonomous vehicle to be charged.

Interesting vid on some MIT guys work on wireless vehicle charging

A wireless world of EVs and AVs: the WiTricity story - YouTube


I think in a couple more years this wireless vehicle charging will become more common.

Tesla must also be working on this for their autonomous taxi service they are planning.

 

[Gale Hawkins]

That's very cool.

The fully self driving EV's will open a floodgate of possibilities.

Just added a vid from some MIT engineers thoughts on wireless vehicle charging and even standardization

The Science Fiction Future continues to happen. Just like Star Trek Next Gen with touch screen computers.
just give it a bit of time.

with these autonomous model 3 and other Taxis being planned, this will be a game changer for sure.

as an aside earlier, I mentioned a family member was looking into buying a 2nd gen Volt, well it has been purchased and I may get to test drive it today- I will admit i am excited to drive an electrified vehicle.:thumbsup:

 

[ultrarunner]

The new charging stations that just went in at the mall took months...

Lots of underground work... a new transformer from the high voltage transmission lines next to the State Highway... guess they foresee the need for vast amounts of power.

One of the Docs was low on charge with her Tesla last year and needed to go beyond her range... I had set up a 120 volt extension cord and she was able to get enough charge to do what she needed.

She was requested charging stations or 240V outlets in the Doctor parking lot... so far it has not happened and she accepted a fellowship and is no longer with us...

I'm sure someone will correct me if I'm incorrect on this :laughing: but wasn't the original concept for Tesla vehicles to have replaceable batteries where you could stop into a 'service station' where they would exchange a depleted battery for a fully charged one in a matter of minutes?

That was what piqued my interest in Tesla way back in 2008 when I heard it from an individual when we were discussing the possibility of NG as a motor fuel.

There were some that tried that concept but it was a disaster when tested.

I think the major drop in battery prices and more and more charging stations killed that idea. For one I want to hang on to my owned LI battery instead of one from a stranger. As ranges move to the 300-600 miles per charge even charging on the road will be a thing of the past for most of us.

I believe Tesla now believes the battery and charging tech will soon increase to a point that this is a step backwards.

NIO in China builds vehicles that work that way and are saying a swap can take place in 6 minutes

This would be very problematic in cold snowy places like Canada and Northern US.
Road salt, corrosion, frozen connectors. Seems like a litany of problems that will crop up especially after a few years of use and swapping.

Maybe someone who knows the Tesla history will chime in on whether that was the plan originally

While that is impressive I think technology is moving past this concept. Change in battery technology will go on for years to come.

The Battery Revolution. Ultra Fast Charging - YouTube

Tesla's Quest for Better Batteries - YouTube

There seems to be a strong desire by Tesla to get away from Panasonic battery dependency. If Tesla pulls off the Maxwell technology that it now owns the other makers may be stuck with dated battery technology.

One factor about Tesla that I think escapes the general public is they are patenting their EV building technology. At some point Telsa patents may be worth more the cars they sell to their cash flows down the road.

Telsa is not a new car company but a new breed of high tech companies. Musk's long range space living plans will use much of the technology he is creating and testing today in his cars and trucks.

Seldom are things as though they may seem.

The question asked about a Supercharger extension cord. Supercharger is Tesla's trademark for high speed DC chargers. The predominate version of Superchargers source 150 kW to the newest Teslas, or "only" 120 kW to mine. My car will charge at a Supercharger at a rate about 3x the 200A service run to my home.

The Tesla Mobile Connector which comes coiled in a pouch in the trunk can use several plug adapters Tesla offers. Most choose NEMA 14-50. Six years ago mine came with 14-50 (240V 50A, runs 40A) and (I believe) 5-15 (common 120V 15A, runs 12A). Extension cords for either of those are relatively easy. The 14-50 is commonly used for large RVs.

The Mobile Connector bundled with new Model 3s maxes at 240V 32A. Tesla Wall Connector (hard wired) can do 240V 80A but not all Teslas can make use of all that on AC.

What are the various combinations of Model 3 variants and suitable high power home chargers?

Looks like an ultra capacitor charging station can’t be far behind. Load up the amps at 20KW and slam dump it into the car when it’s plugged in.

Looks like an ultra capacitor charging station can’t be far behind. Load up the amps at 20KW and slam dump it into the car when it’s plugged in.

Current batteries and vehicle wiring can't take "slam dumping it". Tesla is at the forefront of pushing the limits for charging speeds. My wife's Chevy bolt can handle 32 amps @ 240V when charging from AC. This amounts to a 7.68 KW peak charging rate. When charging from a DC fast charger, it can handle a 50 KW rate. (With either of these methods, the charge rate slows down when the battery passes 80% full.)

That 50KW max charge rate is dwarfed by most Teslas. It hasn't been an issue for us, since we're almost always charging overnight at home. When we're not using the heater or AC, we can get about 240 miles from a charge. We get significantly less in the winter, between the poor traction, studded tires, rolling through slush, and running the heater. It makes a great commuter car. A 150 mile day without charging is a no brainer (at least when we are not running the heater heavily). We don't even think about it, just plug in when we get home. We usually set the car to only charge to 80 or 90% of full, unless we know we have a big day of driving in store. (Lithium batteries "like" being stored not completely full or completely drained - the same is true for cordless lithium tools. The Chevy dealer said it's not a big deal as far as expected battery life goes, but we figured if we don't need that last bit of capacity, why fill it all the way?)
